Title:
Laser beam welding
Document Type and Number:
Japanese Patent JP6000970
Kind Code:
B2
Abstract:
A process is provided for laser beam welding of surface treated steel components. Two steel components, at least one of which is a surface treated steel component, are relatively arranged to form a joint that is to be welded. Using a laser beam, the two steel components are irradiated along the joint so as to heat materials within each of the two steel components to a welding temperature, and thereby form a weld pool. During welding a metallic constituent is introduced into a leading edge of the weld pool, in front of the laser beam along a welding direction. The introduced metallic constituent combines with a species, which is released into the weld pool from the surface treated steel component, to form a compound that is stable within the weld pool at the welding temperature.
